How do we select the proper current transformer for a given application?

In order to select the proper indoor type current transformer for an application, there are four phases need to be addressed:

1- Define customer requirements based on the primary circuit and the metering and protection chains; i.e. define customer requirements in terms of current transformer specifications, key can be summarized as follows:

3- If no suitable CT has been found, you can still check the feasibility of the solution on “ELONET” using the “configured order” option for a given CT type or SE cubicle (note: in case a feasible solution has been found, the configured CT can then be ordered/procured via dedicated supply chain or intra-group purchase team).

4- If still no solution found, you need to fill-in a consultation form (per CT solution required) and send it back to technical support team for feasibility study; consultation form attached.
